Specification of Leiters Patent.

Talented Doe. Tiel,

Application filed January 24:, 1908. Serial No. 412.528.

To all whom. il may concern:

lle it known thaty li, WILLIAM T. Joni-is, u citizen of the United States, residing at. (leder Ra iids, in the county of Linn and Stato oi own, have invented certain new and useful linprt-ivenieiits in l-'liiy-Loadcr Couplings; and l do hereby declare the Jiollowingr to he :i full, clear, and exact descri tfion of the invention, .such as vwill enube others skilled in the nrtl 'to which it appertiiins to make and use the saine.

This invention reliiies to hay-loaders; of liic general type, which are attached to the rear of :i wagon, and rake and deposit the hay thereon. 4

The, ohjcct ofthe invention is to provide u simple, otiicicntY und easily operated coupling whereby the wagon and luiy-louder muy he connected without any lzihor on the part. of the operator.

The nature of the invention will clearly appear from the desrrii'ition and claims Yfollowing, reference heilig had to the acronipanyiug drawings, in which- Figure is a side elevation. illustrating in v improved coupling :is applied to a hayloiulcr. the latter heilig Shown diagrammatirally and without any attempt to illustrate details oi' construction. Fig. 3 is :i lop View of the coupling und Fig. 3 is a central vertical Section of the saine.

Most hay-loaders are so constructed that.- thc elevator which projects over the hziyriufk and deposits ilieraliecl hay thereon, hns a eonsideralily orerlninging weight., usually more than culi he conveniently lifted by one. inail, yas necessary in coupling; ihe tongue of the hay-loader to the rear of the hay wagon. This invention is ilesiffncd to facilitate this operation liv r riding ii coupling' so eonstrueli-.id that uit.` is at all limesl in suitnhle position to connect with the hay wagon hy simply backing` the lat-ter up against. the liar-loader.

rl`luI mechanism cinluidying ihr invention will now he doscrihi-il, rulei'nin-e heine; hud to the drawingizaI wherein tlul dili'erciit. parts are designated h r numerals.

Referring now to the drawings. l indiatcs a` hay-loader elevator and-2 the tongue thereof. 'lhis is uSuall)P attached rigidly7 to thel hay-loader, adjustalily or otherwise. and when raised to suilahlc coupliug` position with the, waron, brings the liar-loader' into proper posit-ion for work. Attarhoil to this tongue is u coupling-hund 2l having au upwardly inclined nose Tf und ii downwardly extending' shoulder 5 to receive the couplinglink t3 which is attached to the rear enfl of the hay wagon :itY sonic `"iiitahle point, such :is the reni' cross-har of the hayracli 7. This link may he u Simple Stirrup, as more clearly shown in Fig. 2.

livoteri inn coupling-head 2l is :i hook 8- ndaptcd to lurnia little distance up and down to release or engage :i coupling-link.

The hook is held in coupling position by u.

shoulder' fl engaging the forward and of :iwl l0, nvoted at ll. rlhis. .uiwl is; oreferahly provided willi a spring i2 atliipieil.

to .torre the forward end downwardly enci so insure engagement with the coupling-- hook, Back of u linger 13 is mounted inother spring l-l adapted to throw the coupling-hook ttm-wurd and upwardly so es io hold it in open position whenever the pew! is disengaged. ln coupling'. he link strik-fos this linger. which at. this time is in iiie position indu-ined in Fig. i and pushes it. hack to a. pointy where the pawl muy engage the (coupling-hook, us shown in Fig. 3., in which position he link is securely held ley tho hook.

Provision is inadc for holding the 'tongue et. any desired elevation, so that. whenever the wan-on is hacked into coupling poniion 'the linll' will he at. the. proper lerel to einggage the coupling! head. This iiienliniiinli. is'hest illustrated in Figs. l and 3.I At ihn rear cud ol the coupling-howl is ,si pun' lugs l5, pierreol lo receive studia lli proie-ring iforwerdlv lroiu a verticiil plate il' uml,

l thehay-loader and passing thenee and fasextending to the top 'of the leg' and 'assinw "through a hole in a top-plate 3G. T ns ro' is provided with a suitable eye 37 by means of which the operator may lift it and with it the ieg 'and elevate to any desired position. The'pawlandlever are eonneeted by a sprn r 38 which tends to press the pawl forwar ly into engaging position with the guide-plate. The guideplate is vprovided with a pair of braee-rods 39 connecting it with the tong-ue Zandserving; to brace and Strengthen it.

In the operation ofv the device the tongue is first raised to a suitable position and eonneeted with the hay wagon, which may be done by simply releasing the pawl 25 and raising the tongue to the proper elevation. In so doing the leg drops to the ground and is automatically locked in that position by the pawl 2l. 'lhe operator then backs the hay wagon toward the hay-loader and the couplingJ is made automatieally. Ile then, by the pull-rod 3T, lifts the ler as high as may be necessary so' as to clear obstructions and it is automatically' lot-,lied in this lifted position. When it is desired to uneouple the loaded wagon from the hay-load`er, the man on the load pulls the eor 2S which produces the double eil'eet ot releasing' the pawl 25, whieh allows the leg' to drop tu suitable holding' position l'or the tongue, and also of disengaging the pawl lt) sons to permit the wagon to uneouple from the hay-loader.

lt. is evident that. th'e tongue is thus mai|i.

tained at', a suitable Aelevation to reiingage the wagon when it is desired to eouple them This is also true regardless of the conformation olf the ground, as it is evident that. the leg will only drop so far as to make eontaet with the surface of the ground,

whether it be. an elevatioin' hollow or level.

'lhe leg is provided with a forwardly and a linger 32- yfor the purpose of proteeting the ha; against accidental breaka e. Should now the, operator forget to pnl? up the leg free from the ground before starting the wagon the leer Will simply drag along on the ground until the shoe strikes a stone or hilloelc, when it will be forced upwardly, and will thus autov inatieally uneouple the loader from the, wagon.

Having thus described my invention what l claim as new and desire to secure by lietters Patent is:

l. ln a hayloader, the combination with a coupling-head ofv a guide-plate atlaehed thereto, a leg mounted to slide along said guide-plate, a pawl pivoled to said guideplate and engaging' with the guide-plate, means for engaging'. and dise'ng'atg'ingi,f said pawl, an auxiliary pawl pivoted tothe guideplate and adapted to engage the leg and means for engi'aginplr and dlsengaging said auxiliary pawl.

ln a bay-loader, the eombination oi a coupling-headl` having' a coupling-hook and a. pawl adapted to engage the saine in eoup ling' position, a guide-plate attaehed to said head. a leg adjustable along' said guideplate, means substantially ,as deserbed lo hohl said legY at any desired position along said guide-plate. an auxiliary panl adapted also toiengage the leg' and hohl it in opposite position as reg'a rds the. other pawlan'd means eonneetingr with said auxiliary pawl and `the coupling-hook panl il'or releasing both thereof by a single :let ofthe operator.

l. in a luly-lomler1 the combination of a eouplingdiead, a 2guide-plate attaehed tl1ereto, a. leg' movable up and down along' said rguide-plate` a pawl to engage it and hohl the guide plate. at any desired elevation, a lever engaging the said pan'l and a lil't.-i'ml eonneeling with said lever hereby the pawl may he disengaged and the leg' lltted bythe same act.
